    <title id='Description'>DataTable with Validation. Double-Click on a Row to enter into edit mode. The editor of the "Ship Country" column passes the validation when minimum 5 characters are entered. "Freight" should be in the 0-1000 interval and "Shipped Date" should be in the 1990-2014 interval. "Order ID" is not editable.</title>
